<H3><A NAME="M4">DESCRIPTION</A></H3>
<B>Tk_MainLoop</B> is a procedure that loops repeatedly calling
<B><A HREF="../TclLib/DoOneEvent.htm">Tcl_DoOneEvent</A></B>.  It returns only when there are no applications
left in this process (i.e. no main windows exist anymore).  Most
windowing applications will call <B>Tk_MainLoop</B> after
initialization; the main execution of the application will consist
entirely of callbacks invoked via <B><A HREF="../TclLib/DoOneEvent.htm">Tcl_DoOneEvent</A></B>.
